A large herbivore which lived on the savannahs of Africa during the Miocene and Pliocene. In contrast with most members of its family it did not walk on its knuckles. This animal family (Chalicotheriidae) does not exist today. But horses, rhinos and tapirs are their closes living relatives. This animal seems to have become extinct in connection with our ancestors inventing big game hunting. If so, it was simply too easy for a prey.
